The KN-8828B allows easy roasting of the coffee for new users, yet sup-

plies complete manual control for those who become advanced in their roasting 

knowledge and are looking for a specifi c taste or roast level. Roast Profi les can 

be saved for later use as well. Physically,  it is the same as our other models. The 

difference is the control panel and user interface. 

In the Auto mode the user will fi nd that with just three pushes of the START button the coffee roast-

ing process will begin. In the manual mode, all parameters of the roasting process can be controlled by the 

user. These modes and how to operate them are fully described in this chapter.

The fi rst thing that you will notice is the colorful LCD display panel. This is the interface between the 

user and the roaster. Let’s begin by understanding what is displayed here. Detailed instructions on how to 

use the various functions of the KN-8828B will be found on pages 14 through 17. 

NOTE

: The display components vary depending on which mode is in use. Only functions that are 

currently available will be illuminated. 

TIME

The countdown 

timer will eject 

the beans if it 

reaches 00:00. 

Format is mm:ss.

TEMPERATURE

If the roast reaches 

the Target Tempera-

ture the beans will be 

ejected. Also shows 

the actual roasting 

chamber temperature.

FAN SPEED

This is used to 

control the speed 

of the main

exhaust fan. 

HEATING ELEMENT 

This displays the level of 

power produced by the 

heating element. Each 

bar represents 10%.

The up and down “Chevrons” are used to 

raise and lower values of various

parameters such as time and fan speed.

SELECT

The circular “Select” arrow 

cycles through the display  

to select which parameter to 

adjust or display. 

Powers up the machine, 

selects modes, and allows 

the machine to be stopped.

Enters the selected mode 

and then begins to roast.

During a roast this will eject the 

beans and begin the cooling 

mode. During programming 

this works as an escape key, 

taking you back one step in the 

process, abandoning changes 

made up to that point.
